求助:aix下rman备份问题

bjzhulei

采用rman定期备份oracle数据库,日志中最后总报这个错,请问高手什么原因
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of delete command at 02/23/2009 19:08:41
RMAN-06091: no channel allocated for maintenance (of an appropriate type)

RMAN>
released channel: ORA_MAINT_DISK_1
我的备份脚本如下:
#!/usr/bin/ksh
#
# Backup database instance PBANK at incremental level 1
#
export ORACLE_SID=DMCOW01
rman target / catalog rman/rman@RMAND << EOF_RMAN
run {
  allocate channel d1 type disk;
  allocate channel d2 type disk;

  BACKUP
    INCREMENTAL LEVEL 1 CUMULATIVE
    FILESPERSET 10
    FORMAT '/orabakpes02/dbsbackup/incr/incr_%T_%s_%p'
    DATABASE;
  
  BACKUP
    FILESPERSET 10
    MAXSETSIZE 10G
    FORMAT '/orabakpes02/dbsbackup/incr/arch_%T_%s_%p'
    SKIP INACCESSIBLE
    ARCHIVELOG ALL;

  release channel d2;
  release channel d1;
}
EOF_RMAN

rman target / catalog rman/rman@RMAND << EOF_RMAN
  allocate channel for maintenance device type disk;
  crosscheck backup;
  delete noprompt obsolete recovery window of 30 days;
  release channel;
EOF_RMAN
#
请高手指点,谢谢

allocate channel for maintenance device type disk;
  crosscheck backup;
allocate channel for delete device type disk
  delete noprompt obsolete recovery window of 30 days;
  release channel;
